Astronomers have confirmed the first discovery of an alien planet in our Milky Way that came from another galaxy. The Jupiter-like planet orbits a star born in another galaxy and later captured by our own Milky Way sometime between 6 billion and 9 bi

A comet visited by a NASA spacecraft is spewing jets of vaporized dry ice into space. "Previously it was thought that water vapor from water ice was the propulsive force behind jets of material coming off of the body, or nucleus, of the comet,"

Scientists are exploring rocket-propelled hopping vehicles that can wander places wheeled rovers only dream of going. The idea is to blast gas from the Martian atmosphere out in jets for thrust. A number of ideas for Martian hoppers have been floated

When an impressive contrail was spotted off the California coast last week, it sparked widespread reports of a mystery missile launch in the area – a theory the Pentagon squashed, but the odd contrail was even seen from space.

SpaceX’s Falcon 9 rocket has won a 2010 Popular Science Best of What's New award in Aviation & Space..
“At SpaceX, we have ambitious goals for the future of human spaceflight. We are working every day to bring about significant breakthroughs tha

Until now, paper planes have basically been flown in schoolrooms and offices. Sometimes the flight ends in trouble for the would-be aeronautical engineer. But now a milestone in paper airplane flight technology has been achieved: the first paper airp

Rocket maker and NASA commercial spaceflight hopeful Space Exploration Technologies (SpaceX) has raised $50.19 million in new equity financing from 16 investors, according to a Nov. 9 filing with the U.S. Securities and Exchange Commission.

In a step toward solving the global energy crisis, a new plan aims to harvest the sun's energy from space with satellites then beam it down to Earth.
The initiative, announced Nov. 4, is spearheaded by former president of India A.P.J. Kalam and th

In order for your assertion to be true, one half the Earth would not be able to see the moon without traveling to the other half. Since we know that that's not the case, and we know that the moon does not rotate, a permanent dark side is an impossibi

A NASA spacecraft has beamed back the first close-up photos from its rendezvous with a comet — and the images show an ice ball that looks like a giant chicken drumstick, or perhaps a peanut or bowling pin.

For $150 billion, the National Aeronautics and Space Administration could have sent astronauts back to the Moon. The Obama administration judged that too expensive, and in September, Congress agreed to cancel the program.

The Kepler Space Telescope doesn’t just look for planets. By listening to subtle vibrations of the stars in its field of view, the telescope is recording a stellar symphony that gives an unprecedentedly accurate view of the inner lives of stars.

World renowned astrobiologist Chandra Wickramasinghe is spitting mad. The eminent scientist recently reiterated the charge he made against the National Aeronautics and Space Administration back in 2008. "The discovery of liquid water on Mars combine

Virgin Galactic, an offshoot of billionaire Richard Branson's London-based Virgin, plans to compete in the upcoming race to develop orbital space vehicles, Branson said. Virgin Galactic was currently in discussions with 2 companies about teaming up w

Building a satellite and launching it into space was once a multi-million dollar proposition. But even though miniaturization and easy-to-adapt technology formats like the CubeSat have brought down the costs of building satellites

A huge alien planet discovered in a system with two suns akin to the fictional "Star Wars" world of Tatooine is forcing astronomers to rethink their theories about how gas giant planets form.
The two stars are close enough together that the leadin

A rocket sent crashing into the Moon last year kicked up several hundred pounds of water, silver, mercury and other surprising chemicals. NASA sent a rocket to the permanently shadowed moon crater Cabeus to see what would, literally, pop up.

The world’s first private passenger spaceship will pass another milestone toward its commercial lift-off Friday, at a remote spaceport in the New Mexico desert.
Flamboyant British multi-millionaire Richard Branson will commemorate the completion o

The vast plains of Mars may be the most promising place beyond Earth for human colonization, but is it enough for a one-way trip to the Red Planet? A manned one-way mission to Mars would not only make economical sense, but mark the beginning of long-

The National Aeronautics and Space Administration today released data that the Moon has at least enough water to fill 1,500 swimming pools. The dream of space factories and mining operations has long been a goal of lunar enthusiasts. The belief the M

Astronomers believe they've found the oldest thing they've ever seen in the universe:
Hidden in a Hubble Telescope photo is a small smudge of light calculated to be a galaxy from 13.1 billion years ago. That's a time when the universe was just 600
